Based on half-yearly average temperature data following points have been concluded from the year 1978 to the year 2019. Refer to figure no 3. i. Ist half-year The wettest decade was the year 1998-2007 with 114.88 mm precipitation and the driest decade was the year 2008-2019 with 102.69 mm precipitation. The average maximum precipitation was decreased by 0.85 % in the decade 1988-1997 compared to the year 1978- 1987 and increased by 5.80 % in the year 1998-2007 compared to the year 1988-1997 and again decreased by 2.89% in the year 2008-2019 compared to the year 1998-2007. The average precipitation in the year 2008- 2019 were 2.91%, and 2.06% higher than the year 1988- 1997, and the year 1978-1987 respectively. The average precipitation from the year 1978 to the year 2019, was 107.63 mm. Fig. 3: Total precipitation with half-yearly precipitation graph for the year 1978-2019 ii. IInd half-year The wettest decade was the year 1988-1997 with 715.82 mm precipitation and the driest decade was the year 1998-2007 with 443.31 mm precipitation. The average maximum precipitation was increased by 0.85 % in the year 1988-1997 compared from the year 1978- 1987 and decreased by 5.80 % in the year 1998-2007 compared to the year 1988-1997 and again increased by 2.89% in the year 2008-2019 compared to the year 1998-2007. The average precipitation in the year 2008- 2019 were 2.06% and 2.91% decreased compared to the year 1978-1987 and the year 1988-1997 respectively and 2.89% higher compared to the year 1998-2007. The average precipitation from the year 1978 to the year 2019 was 569.58 mm. The decade 1988-1997 was recorded the highest precipitation with the average 830.70 mm and decade 1998-2007 was recorded with minimum precipitation of 551.60 mm. f) Temperature data Based on data it observed that the average maximum temperature was decreased in decade 1998- 2007 for January to March, May, and June and again increased in the decade 2008-2019. The maximum temperature was increased throughout from the year 1978 to the year 2019 for April, November, and December. The average minimum temperature was increased from the year 1978 to the year 2019 for January, July, November, and December. The minimum temperature was increased from the year 1978 to the year 1997 and decreased in the year 2008-2019 for February, March, and October. The yearly average maximum and minimum temperature data has prepared and given in table 9, showing that the year 1998-2007 were received maximum temp with 34.80°C and the year 2008-2019 were the lowest maximum temp 34.28°C. The average minimum temperature was maximum in the year 2008- 2019 and the lowest were in the year 1988-1997 with 12.29°C, and 10.21°C, respectively. Further it shown that average minimum temperature was increased rapidly, the year 2008-2019 was recorded 1.44°C & 2.08°C temperature higher than the average temperature of the year 1978-1987, and the year 1988- 1997, respectively. The average maximum temperature were decreased in the year 2008-2019 with 0.28°C, and 0.52°C compared to the year 1978-1987 and the year 1998-2007, respectively.
